Yes, it does.
For me, its the red cushions (particularly the 'Love' one), the shiny ottoman, the style of bed frame.
Additionally, imo the lamps are far too small to be useful for reading in bed.
We don't have any neutral colours in our home and actually originally accessorised our De Nimes (blue) main bedroom with large red vintage lamps, but found that the shiny red ceramic texture didn't sit well in the space. We do however have a large, red picture frame hanging on the wall behind the bed and somehow that works!
@Readinggirl I think a more neutral scheme as per the above pics might work as it would create a restful, calming space. You'd need to add lots of textures to layer the room so it didn't appear one dimensional. Obviously your red blinds would then be the outlier...or have to be sacrificed.
Alternatively, go for full on jewel colours and embrace the red (a cerise would work better). If I were doing that I'd colour-drench the whole room in a deep, saturated tone such as emerald green, including up onto the ceiling, to make it cosy and cocooning.
